She snaps at the anal fin to take the ‘eggs’ in her mouth and then the male expels the roe, which fertilizes the eggs in the female’s mouth.Īfter the eggs have hatched, they remain in the female’s mouth. These spots resemble eggs, which makes the female think she has forgotten eggs. He has so-called egg spots (white or yellow dots) on his anal fin. When the female takes the eggs in her mouth, they are not yet fertilized. A short explanation about the egg spot method. The female takes the eggs in her mouth and they are fertilized by the male using the egg spot method.Ī nest usually has about 20 eggs at a time, which are incubated in the mouth of the female. The female deposits the eggs in the sand. The breeding of Iodotropheus sprengerae is quite simple. This fish will eat almost anything, but make sure there is sufficient variety between live food, frozen food, vegetable and dry food. The male does not form territory and can be kept together with other Malawi cichlids. It is, therefore, best to keep one male with three or four females. However, the males can sometimes be aggressive among themselves. Iodotropheus sprengerae is quite calm and peaceful. Despite the fact that these fish do not dig, a sandy bottom is highly appreciated. By stacking the stones, more holes are created. The aquarium should be set up with rocks so that burrows are formed. An aquarium of at least 1.20 meters is therefore necessary. The AquariumĪlthough Iodotropheus sprengerae are not very large, they do need space. This variant has been described by Jay Staufer as Iodotropheus declivitas and later regarded by Ad Konings as a junior synonym.
Iodotropheus sprengarae at 18 meters depth with poor visibility at Makokola Reef. Originīoadzulu Island, Mokokola Reef, the islets of Chinyankwazi and Chiyamwezi, Lake Malawi. The ground color of this fish is rust brown with a purple glow. The males grow to a maximum of 12 centimeters and the females about 9 centimeters. In conclusion, three times daily feeding is recommended the best application for profitable commercial cultures of rusty cichlid due to decreasing labor.As with many cichlids, the males and females of the Iodotropheus sprengerae have different lengths. The cost-effective groups of the present experiment were F3 and F4 groups. For the coloration parameters, the final redness ( a*) of F4 group was the highest (P <. Although the average seed production (ASP) of F3 (mean of 98 ± 8.89) and F4 (mean of 93 ± 4.04) were significantly similar, the highest fecundity was observed in F4 group. The highest final mean total length (FMTL) was found in F3 group with 9.07 cm (P <.
At the end of the trial, final mean weight (FMW) and specific growth rate (SGR) increased with increasing feeding frequency (P <. Fish were stocked in each tank at a density of 10 individual with sex ratio 1:4 (male:female) and they were fed with a commercial ornamental cichlid diet to near satiation.
RUSTY CICHLID TRIAL
The trial was carried out in 15 100-L fiberglass circular tanks conducted to 4000-L freshwater recirculating system with three replicates for 16 weeks. In the present study, the effects of five different feeding frequencies including every other day (2F1), one (F1), two (F2), three (F3), and four (F4) times daily on growth, reproduction, the coloration of rusty cichlid (mean body weight 2.04 ± 0.01 g and mean total length 4.35 ± 0.01 cm) were investigated.
